Around 75% of the carbon dioxide captured is effectively converted into energy here, and the name is derived from the fact that the carbon dioxide is converted into a 3-carbon compound.

Photosynthesis is the method that plants use to make their own food.

Photosynthesis is the procedure all plants go through to make food.

In Photosynthesis, photons of light are absorbed by chlorophyll molecules, causing them to donate a high-energy electron that is put to work making NADPH and pumping protons to produce ATP. In this section of the lab you will examine recent evidence that proteins embedded in the thylakoid membranes within the chloroplasts of photosynthetic organisms are acting as an antenna to facilitate light capture.

Enzymes involved in photosynthesis and respiration - …

The fundamental principle of photosynthesis is that plants open and close the stomata (pores) on the leaves, and thus control the amount of carbon dioxide and oxygen that passes through them.

Enzymes are presented in the plants cells and the energy for the first stages in the synthesis comes from sunlight, this is called photosynthesis.

Lab 10 - Enzymes and Photosynthesis.

These depend on the frequency and the intensity with which the stomata of the plants open and close, the amount of transpiration (evaporation of water from the stomata) that occurs, the amount of sunlight and heat that the plant is subjected to and the ratio of carbon dioxide consumed by the plant to the amount of water lost through transpiration (this figure is known as the Water Use Efficiency ratio).

Enzyme Activity in Photosynthesis | Synonym

Most enzymes work fastest in neutral conditions. Making the solution more acidic or alkaline will slow the reaction down. At extremes of pH the reaction will stop altogether. Some enzymes, such as those used in digestion, are adapted to work faster in unusual pH conditions and may have an optimum pH of 2 (very acidic) if they act in the stomach.

Some organisms employ even more radical variants of photosynthesis

Enzymes will work best if there is plenty of substrate available. As the concentration of the substrate increases, so does the enzyme activity. However, the enzyme activity does not increase without end. This is because the enzyme can't work any faster even though there is plenty of substrate available.

Remember the role of enzymes in photosynthesis

The energy released by respiration is used to make large molecules from smaller ones. In plants, for example, sugars, nitrates and other nutrients are converted into amino acids. Amino acids can then join together to make proteins. The energy is also used:

During the process of photosynthesis, plants use light ..

For the plant to keep on photosynthesising at a steady rate there needs to be plenty of water and the temperature needs to be kept at a certain level because once carbon dioxide is no longer the limiting factor simply giving the plant more wont have any effect.

How do humans use photosynthesis?

Light intensity: It is impossible for plants to photosynthesise in the dark and they can only photosynthesise slowly in dim light, this is because the light energy splits up the water into hydrogen and oxygen it does this by releasing a highly charged electron when sunlight is
